  • Publication number: 20220366798
    Abstract: A geo-containment system includes at least one unmanned vehicle and an enforcement system that is onboard the unmanned vehicle and configured to limit travel of the unmanned vehicle based, at least in part, on predefined geospatial operational boundaries. Such boundaries may include a primary boundary and at least one secondary boundary that is spaced apart from the primary boundary a minimum safe distance. The minimum safe distance is determined while the unmanned vehicle is traveling. The minimum safe distance is determined using state information of the unmanned vehicle and/or dynamics of the unmanned vehicle. The state information includes at least position and velocity of the unmanned vehicle. The enforcement system is configured to alter and/or terminate operation of the unmanned vehicle if the unmanned vehicle violates the primary geospatial operational boundary and/or the secondary geospatial boundary.

  • Patent number: 10490088
    Abstract: A Geo-containment system includes at least one unmanned aircraft and a control system that is configured to limit flight of the unmanned aircraft based, at least in part, on predefined Geo-spatial operational boundaries. These boundaries may include a primary boundary and at least one secondary boundary that is spaced apart from the primary boundary a minimum safe distance. The minimum safe distance is determined while the unmanned aircraft is in flight utilizing state information of the unmanned aircraft and dynamics and dynamics coefficients of the unmanned aircraft. The state information includes at least position and velocity of the unmanned aircraft. The control system is configured to alter or terminate operation of the unmanned aircraft if the unmanned aircraft violates the primary Geo-spatial operational boundary or the secondary Geo-spatial boundary.
